Co-Parenting Nightmare! Jenelle Evans FLIPS OUT On Ex Nathan Griffith's Over Custody Of Kaiser

Over the weekend, Nathan celebrated his girlfriend Ashley Lanhardt’s birthday with family and friends. After Jenelle allegedly saw photos and videos from the birthday weekend, she assumed Nathan’s mother Doris Davidson did not supervise the visits.

“She texted his mom and her husband David [Eason] texted Nathan Sunday morning,” an insider close to Nathan said. “Nathan’s mom was with Kaiser. They stay with his mom when they are in town.”

The insider claimed that Jenelle demanded to speak to her son even though he was sleeping. “It’s just sad that they were forced to wake up just so she could hear his voice because she didn’t believe he was there,” the source said. “Where else would he be?”

“Nathan and his mom always play by the rules because they know how she is,” the insider said. “It’s her way of controlling Nathan.”

Nathan isn't the only one that has to deal with Jenelle! His girlfriend is allegedly “scared” of Jenelle. “Anytime Ashley is around Kaiser there is an issue,” the source said. “She has to hide it.”

Nathan’s mother has custody of Kaiser every other weekend.

Within the last week, Jenelle's feuds with her co-stars Leah Messer and Kailyn Lowry exploded after David made unnecessary comments regarding Leah's daughter's cheer-leading makeup.

Then Nathan completely dissed his ex with a cryptic tweet! He wrote, "@KailLowry @Javimarroquin9 @NerdIn_aCoolKid @ChelseaHouska @PapaRandlicious @jcalvert505 @TM2LeahDawn @coreysimmsMTV I’m just throwing this out there... we are all on the same team. So, usually if you attack one of us, most of us are going to defend one another. #notsorry #loner." Jenelle was not tagged in his post...ouch!
